These successful exploits, and Gaul entirely pacified, gave to the barbarian peoples so high an opinion of the Roman power, that the nations beyond the Rhine, particularly the Ubii, sent deputies to Cæsar, offering hostages and obedience to his orders. Anxious to proceed to Italy and Illyria, he commanded the deputies to return to him at the commencement of the following spring, and placed his legions, with the exception of the 12th, in winter quarters, in the countries of the Carnutes, the Andes, and the Turones, neighbouring upon the localities where Crassus had been making war.272 They were probably échelonnés in the valley of the Loire, between Orleans and Angers.
Expedition of Galba into the Valais.
X. Before he departed for Italy, Cæsar sent Servius Galba, with a part of the cavalry and the 12th legion, into the country of the Nantuates, the Veragri, and the Seduni (peoples of Chablais and Lower and Upper Valais), whose territory extended from the country of the Allobroges, Lake Léman, and the Rhone, to the summit of the Alps. His object was to open an easy communication with Italy by way of these mountains, that is, by the Simplon and the St. Bernard, where travellers were continually subject to exactions and vexations. Galba, after some successful battles, by which all these peoples were subdued, obtained hostages, placed two cohorts among the Nantuates, and the rest of his legions in a town of the Veragri called Octodurus (Martigny). This town, situated in a little plain at the bottom of a glen surrounded by high mountains, was divided into two parts by a river (the Drance). Galba left one bank to the Gauls, and established his troops on the other, which he fortified with a fosse and rampart.
Several day had passed in the greatest tranquillity, when Galba learnt suddenly that the Gauls had during the night evacuated the part of the town which they occupied, and that the Veragri and the Seduni were appearing in great numbers on the surrounding mountains. The situation was most critical; for not only could Galba reckon on no succour, but he had not even finished his retrenchments, or gathered in his provisions in sufficient quantity. He called together a council, in which it was decided, in spite of the opinions of some chiefs, who proposed to abandon the baggage and fight their way out, that they should defend the camp; but the enemies hardly gave the Romans time to make the necessary dispositions. Suddenly they rush from all sides towards the retrenchments, and throw a shower of darts and javelins (gæsa). Having to defend themselves against forces which are continually renewed, they are obliged to fight all at once, and to move incessantly to the point that are most threatened. The men who are fatigued, and even the wounded, cannot quit the place. The combat had lasted six hours: the Romans were exhausted with fatigue. Already they began to be short of missiles; already the Gauls, with increasing audacity, were filling up the fosse and tearing down the palisades; already the Romans were reduced to the last extremity, when the primipilus, P. Sextius Baculus, the same who had shown so much energy in the battle of the Sambre, and C. Volusenus, tribune of the soldiers, advise Galba that the only hope which remained was in a sally. The suggestion is adopted. At the command of the centurions, the soldiers confine themselves to parrying the missiles, and take breath; then, when the signal is given, rushing on all sides to the gates, they fall upon the enemy, put him to rout, and make an immense slaughter. Of 30,000 Gauls, about 10,000 were slain.[273] In spite of this, Galba, not believing himself in safety in so difficult a country, in the midst of hostile populations, brought back the 12th legion into the country of the Allobroges, where it wintered.[273a]
CHAPTER VI.
(Year of Rome 698.)
Insurrection of the Maritime Peoples.
I. WHILE Cæsar was visiting Illyria and the different towns of the Cisalpine, such as Ravenna and Lucca, war broke out anew in Gaul. The cause was this. Young P. Crassus was in winter quarters with the 7th legion among the Andes, near the ocean; as he fell short of wheat, he sent several prefects and military tribunes to ask for provisions from the neighbouring peoples. T. Terrasidius was deputed to the Unelli,273 M. Trebius Gallus to the Curiosolitæ, and Quintus Velanius, with T. Silius, to the Veneti. This last people was the most powerful on the whole coast through its commerce and its navy. Its numerous ships served to carry on a traffic with the isle of Britain. Possessed of consummate skill in the art of navigation, it ruled over this part of the ocean. The Veneti first seized Silius and Velanius, in the hope of obtaining in exchange for them the return of the hostages given to Crassus. Their example was soon followed. The Unelli and the Curiosolitæ seized, with the same design, Trebius and Terrasidius; they entered into an engagement with the Veneti, through their chiefs, to run the same fortune, excited the rest of the neighbouring maritime peoples to recover their liberty, and all together intimated to Crassus that he must send back the hostages if he wished his tribunes and prefects to be restored.
Cæsar, then very far distant from the scene of these events, learnt them from Crassus. He immediately ordered galleys to be constructed on the Loire, rowers to be fetched from the coast of the Mediterranean, and sailors and pilots to be procured. These measures having been promptly executed, he repaired to the army as soon as the season permitted. At the news of his approach, the Veneti and their allies, conscious that they had been guilty of throwing into fetters envoys invested with a character which is inviolable, made preparations proportionate to the danger with which they saw they were threatened. Above all, they set to work making their ships ready for action. Their confidence was great: they knew that the tides would intercept the roads on the sea-coast; they reckoned on the difficulty of the navigation in those unknown latitudes, where the ports are few, and on the want of provisions, which would not permit the Romans to make a long stay in their country.
Their determination once taken, they fortified their oppida, and transported to them the wheat from their fields. Persuaded that the country of the Veneti would be the first attacked, they gathered together all their ships, no doubt in the vast estuary formed by the river Auray in the Bay of Quiberon. (See Plate 12.) They allied themselves with the maritime peoples of the coast, from the mouth of the Loire to that of the Scheldt,274 and demanded succour from the isle of Britain.275
In spite of the difficulties of this war, Cæsar undertook it without hesitation. He was influenced by grave motives: the violation of the right of nations, the rebellion after submission, the coalition of so many peoples; above all, by the fear that their impunity would be an encouragement to others. If we believe Strabo, Cæsar, as well as the Veneti, had other reasons to desire this war: on one side, the latter, possessed of the commerce of Britain, already suspected the design of the Roman general to pass into that island, and they sought to deprive him of the means; and, on the other, Cæsar could not attempt the dangerous enterprise of a descent on England till after he had destroyed the fleet of the Veneti, the sole masters of the ocean.276
War against the Veneti.
II. Be this as it may, in order to prevent new risings, Cæsar divided his army so as to occupy the country militarily. The lieutenant T. Labienus, at the head of a part of the cavalry, was sent to the Treviri, with the mission to visit the Remi and other peoples of Belgic Gaul, to maintain them in their duty, and to oppose the passage of the Rhine by the Germans, who were said to have been invited by the Belgæ. P. Crassus was ordered, with twelve legionary cohorts, and a numerous body of cavalry, to repair into Aquitaine, to prevent the inhabitants of that province from swelling the forces of the insurrection. The lieutenant Q. Titurius Sabinus was detached with three legions to restrain the Unelli, the Curiosolitæ, and the Lexovii. The young D. Brutus,277 who had arrived from the Mediterranean with the galleys,
